Is it possible to talk about fashion, faith or fantasy in fundamental science?

The Universe is not interested in human fashion. Science cannot be interpreted as faith, because scientific postulates are constantly subjected to strict experimental testing and are discarded as soon as dogma begins to conflict with objective reality. And fantasy generally neglects both facts and logic. Nevertheless, the great Roger Penrose does not want to completely reject these phenomena, because scientific fashion can be the engine of progress, faith appears when a theory is confirmed by real experiments, and without a flight of fancy one cannot comprehend all the oddities of our Universe.

In the chapter "Fashion" you will learn about string theory - the most fashionable theory of recent decades. “Faith” is dedicated to the tenets on which quantum mechanics stands. And “Fantasy” concerns nothing less than theories of the origin of the Universe known to us.
